These problems are usually caused by a hardware problem. As you have installed Windows and different versions of Windows several times, it almost certainly a hardware problem. Typically, the problem is caused by defective memory. A clue that it may be a memory problem, is that it appears to happen when you load-up memory with large files. There are many other possibilities… some examples: interrupt conflicts, defective or cheap motherboard, noise in power supply voltages, display drivers, incorrect CMOS settings, hot CPU, and overclocking. If the computer were in my shop, I would:
Clean the computer interior and power supply with compressed air
Do a visual inspection
Reseat memory and expansion boards
Run diagnostics, etc.
Replace the memory. Larry
